Product Overview

The streamlined design of the Wellworth toilet tank has been a KOHLER staple since 1936. Now equipped with high-efficiency components, this almond-colored tank releases 1.28 Gal. of water per flush, meeting the EPA’s standards for superior water conservation. It represents a 20% decrease in water usage compared to ultra-low-flow toilets (1.6 GPF) and a monumental boost in efficiency compared to toilets commonly installed in the 1980s and early 1990s (3.5 GPF). With a canister flush valve and gravity-assisted syphoning, you’ll find the thrust of this tank is comparable to that of yesteryear’s inefficient toilets.
  • According to the EPA, a high-efficiency toilet like the Wellworth can reduce a family’s water usage by 20-60%, resulting in lower utility bills
  • Class Five flushing technology furnishes leak- and plug-free throughput
  • Gravity-assisted siphoning action delivers extra flushing oomph
  • Canister flush valve maximizes flush performance and inhibits deterioration and warping
  • Releases 1.28 Gal. of water per flush
  • Wellworth toilet bowl (model K-4199) sold separately
  • Matches up with almond toilet bowls in the KOHLER Wellworth lineup
  • Conforms to EPA WaterSense standards, which translates to 20% less water usage than ultra-low-flow 1.6 GPF toilets
  • Supply line not included
  • Outfitted with left-side trip lever
  • May qualify for rebates from your municipality or utility provider
  • Also available in black black, white and biscuit colors

After carefully installing this Kohler tank, the gasket between the tank and bowl failed within a couple of weeks so, I've had to purchase a new gasket kit and re-install. I've run out of patience with this brand and now looking forward to replacing the tank and bowl with a different brand.

Rated 5 out of 5 by from Replacement tank. Couldn't stop a leak in my old Kohler tank (K-4620) replaced old tank w/ this K-4636-0 and it fit perfectly. Make sure your Kohler has a 3 bolt pattern at bottom of tank. Easy installation.
